The above snippet basically means it is making a get request to the electron to enable microphone and it’s sending codes other than 200 which is causing to print the “wrong debugging microphone…” etc. So basically the issue persists in the npm start command meaning the electron

@wjdw87 I hit something similar to this, yes. (Heh, sound familiar?) In my case, electron couldn’t access the RPi’s camera. The new version of Chromium has implemented a security “feature” that won’t let it access media hardware without a secured connection. You could try using https and see if that solves it.
